What is the optimal process cycle time and how can you determine it?

1 Identify the process scope and boundaries

The first step to determine the optimal process cycle time is to identify the process scope and boundaries. This means defining what the process is, what are its inputs and outputs, who are the customers and suppliers, and what are the start and end points of the process. You can use a SIPOC diagram (Suppliers, Inputs, Process, Outputs, Customers) to capture this information in a concise and visual way. A SIPOC diagram helps you to focus on the essential elements of the process and avoid getting lost in the details.

2 Map the current process flow and activities

The next step is to map the current process flow and activities. This means documenting how the process is actually performed, what are the steps involved, who is responsible for each step, what are the resources and tools used, and what are the outputs and outcomes of each step. You can use a process flowchart or a value stream map to illustrate the current process flow and activities. A process flowchart shows the sequence of steps and the decision points in the process. A value stream map shows the value-added and non-value-added activities, as well as the time and inventory data, in the process.

3 Analyze the current process cycle time and performance

The third step is to analyze the current process cycle time and performance. This means measuring how long it takes to complete the process and each activity, what are the sources of variation and waste, how often errors or defects occur, and how satisfied are the customers and suppliers with the process. You can use various tools and methods to analyze the current process cycle time and performance, such as histograms, control charts, Pareto charts, fishbone diagrams, and root cause analysis. These tools and methods help you to identify the gaps and opportunities for improvement in the process.

4 Define the target process cycle time and performance

The fourth step is to define the target process cycle time and performance. This means setting the desired or expected time and performance levels for the process and each activity, based on the customer requirements, the business goals, and the benchmarking data. You can use SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) to define the target process cycle time and performance. SMART criteria help you to ensure that your targets are clear, realistic, and aligned with your objectives.

5 Implement and monitor the process improvements

The final step is to implement and monitor the process improvements. This means applying the changes and solutions that will reduce or eliminate the variation and waste, increase the value-added activities, and enhance the quality and customer satisfaction of the process. You can use the PDCA cycle (Plan, Do, Check, Act) to implement and monitor the process improvements. The PDCA cycle helps you to test the effectiveness of your improvements, evaluate the results, and make adjustments as needed.
